New Build destroy/rewrite MetaQuotes custom indicators

 
I am experiencing from Build 180 up, an error/bug. When I upgrade to a new Build, all my custom indicators originally published by MetaQuotes (Stochastic, OsMA, etc.) are rewitten with their original code destroying all my corrections or my own versions with the same name :(. Not happy with that, I hope this is not a feature or you guys are executing a Copyright perhaps :) ?

Perhaps files were overwritten. Bad luck...

Wouldn't the easiest thing to be just rename your customised versions ?
